Low latency mgp request handling for positioning

Abstract

Methods, apparatuses, and computer-readable storage medium for positioning are provided. An example method at a base station may include transmitting, to a user equipment (UE), a location request requesting location information from the UE. The example method at the base station may further include receiving, from the UE, an acknowledgment acknowledging the location request. The example method at the base station may further include transmitting, to the UE based on the received acknowledgment, a measurement gap (MG) request associated with a location management function (LMF) for the UE to measure its location based on the transmitted location request.
